. To all whom it may concern:

Be it known that we, James N. BROKAW,

a citizen of the United States, residing at Tacoma, in the county ofPierce and State .of Washington, and. MnR'roN L. DODGE, a.

citizen of the United States, residing at Seattle, in the county ofKingand State of Washington, have invented new and useful Improvements inMethods of Forming Staves and Machines Therefor, of which the followingis a specification.

This invention relates to the method of forming staves and machinestherefor and consists in certain improvements in the constructionthereof as will be hereinafter fully described and pointed out in theclaims.

pail. The blanks are then carried through the machine and the crozeformed of proper diameter'and at-a proper angle and the ends sawed atthe proper angle with relation to the croze and finished ends of thestaves. The staves are then sawed giving the edges a radial directionand the right difference in width to make the difference in the diameterat the top and bottom of the pail. In form- I ing tubs or pails withstaves of this kind, the

staves are practically finished before assembling so that the pail ortub needs no further finishing after they are assembled. In this way thelabor involved in forming such articles is very greatly reduced and thewaste of material is also somewhat reduced.

The invention is'illustrated in the accom- I machine.

1 marks the frame of the machine. A feed table 2. extends laterally fromthe machine, the frame being provided with an extenslon 1 to which thetable is attached. Side bars 3 are secured above the table by means ofposts 4. The guide bars are designed to engage the ends of the blanks asthey are fed to the machine. A feed belt 5 has one'span just above thelevel of the table 2 so as to engage and carry forward blanks depositedon the table. The belt 5 is carried by the pulleys 6 and 7 The pulley 6is mounted on a shaft 8 carried by the bearing 9 secured to theunderside of the table. The

pulley 7 is carried bya shaft 10 journaled in bearings (not shown) inthe extension 1. A sprocket wheel 11 is secured to the shaft 10.' Asprocket chain 12 operates on the sprocket 11 and communicates movementto thesprocket 11 from a sprocket 13 (see Fig. 7). The sprocket 13 ismounted on a shaft 14 forming one of the driving elements of themachine.

The blanks are placed on the table edgewise as clearly shown in Fig. 4and are carried forward againsta carrier 15. The carrier 15 is mountedon the shaft 14 (see Fig. 7), the shaft having shoulders 16 againstwhich the carrier is forced by a nut 17 arranged at the end of the shaft14.

The shaft 14 is mounted in bearings 18 in the frame. A gear 19 is fixedon the end of the shaft (see Figs. 1 and 2). The gear 19 meshes a pinion20 and the pinion 20 is fixed on a shaft 21. The shaft 21 is mounted inbearings 22' (see Fig. 3). A gear 23 is fixed on the shaft 21. outsidethe gear 20. The gear 23 meshes a gear 24. The gear 24 is mounted on ashaft 25 and the shaft 25 is journaled in bearings 26 arranged-on therier and which as they come into engagement with the edge of a blank asA (see Fig. 4)

carry this blank forward with it'separating I it from the pile. As theblank is advancedon the carrier it moves under a spring pressed shoe(see Figs. 4. and 7), the shoe being placed in a socket 31 in backings32 andthe springs (not shown) actuating said shoe being arranged inspring pockets 31 The backings 32are mounted on a shaft 33 and arelocked in adjustment by the set screws 34. The shaft 33 extends througha post 35 extending upwardly from the frame and is clamped in positionby a nut 36 on the end of the shaft. I v

It will be noted that the carrier 15 is tapered and this taper isexactly the taper or flare of the tub or pail and the blank is moved ina circular path, the radius of the curve being the radius of thefinished pail.

' A cutter 37 is in the path of the blank as it is carried forward bythe carrier 15 and cuts the croze in the stave. This croze, it willbenoted, willhave the proper curve and relation for the finished pail byreason of the direction of movement given to the blank; The cutter37 iscarried by a shaft 38 and the shaft 38 is mountedin bearings 39-(seeFig., 7). -The bearings are carried by-the posts 40 extending from. amovable bracket 41. w This bracket 41 is mounted in guides 42 (see'Fig.2) at the side of the so as to vary the position of the cutter 37 frame.It can be adjusted by the screw 43 r for different sizes of carriers 15and the vmovable bracket40 is locked by the screws 44 (see Fig. 5).ranged on the shaft 38 between the bearings 39 and a belt 46 drives theshaft and cut- 1 ter 37 'Saws 47 are mounted on the shaft 48-.

1 They are in position to engage the blank as A as the carrier reachesthe upper part of its movement. They are so dlstanced as to give theblank exactly the right length and are in parallel relation and operateupon the blank at the proper angle so as to make the top and bottomof'the finished staves level when assembled in the pail or tub.

, The shaft 48 is mounted in bearings 49, one of these bearings beingcarried by the post '50, another by the post 35, and the third bearing'by a post 35 (see Fig.1). A pulley 51 is fixed on the shaft 48 and abelt 52is arranged to drive the pulley and shaft and cut-off saws.

After this, operation theblank is carried forward to mechanism fortrimming and A drive pulley 45 is ari shaping the edges. As the carrier15 moves forward it is carried onto the guide bars 53 mounted in theframe, the bars having fingers 54 extending up into the carrier 15 (seeFig. An extractor having arms 55 mounted on a wheel 56 is sotimed as tobring an arm 55 back of thestave or blank as it is expelled from underthe spring-actuated shoe 30. The. extractor wheel 56 is carried by ashaft 57. The shaft 57 is mounted in a bearing 58, the bearing 58 beingcarried by a post 58 movable laterally on the frame toacconnnodatedifferent sizes of carriers (the adjusting mechanism notbeing shown). The shaft57 is connected with a link or tumbler shaft 59by a knuckle joint 60 and the shaft 59 is connected by a knuckle joint61' with a shaft 62 (see Fig. 2). The shaft 62 is mounted in bearings 63arranged in the post on, the frame. A gear 64 is fixed on the end of theshaft 62 and: meshes a gear 19 so that the extractor wheel 56 isproperly timed with relation to the carrier 15. It will be noted thatthe carrier has four dogs 29, the extractor three arms 55 and thattheextractor by reason of thevvariation in size in the gears 19 and 64 isarrangedto move more rapidly than the carrier 15 so that when the blankand buttons forcing them outwardly, the

ends of the pins having collars 66 holding the pins in the guides.

After the blank has been advanced some distance by the arms 55 it isengaged by a transfer lever 69. The transfer lever has a yielding arm 69at its upper end or atthe point of engagement with the blank, the

yielding arms being mounted on the pins 7 0 on the rigid arm 71, A strap72 extends at one side of the rigid arm. A spring 7 3 tends to push theyielding arm 69 forward. The strap 7 4 at the opposite side of the rigidarm 71 is provided with aset screw 7 5 which limits the forward movementof the yielding arm 69 under the influence of the spring 73.

The arm 69 is] mountedon the rock shaft 7 6 (see Fig. 4). The rock shaft76 is carried in bearings 77 (see Fig. 2). The rockarm 78 is fixed onthe end of the shaft 76 and is connected by means of a pitman 79 with acrank '80 on the gear 23. In this manner the arm 69* is given a rockingmove- 'ment timed in relation to the other feeding elements of themachine. In order to vary .the throw of the arm. 69 the pitman 79 has anadjustable link 81.. The transfer lever 69 having engaged the blank onthe guide bars 53, the blank is forced forward under the hook arms 82(see Fig. 4) and into position against a stop 87, the adjusting link 81permitting a nice adjustment of the transfer lever 69 so as to bring theblank to the posiwhich the chain travels.

be adjusted for difierentwidths of blanks by loosening the screws 88and-moving it outwardly or inwardly, the slots being provided to permitthis adjustment.

The blank as A is carried onto the guide bars 90. A groove 91 isarranged'in the frame below the guide bars 90 and extends the fulllength of the frame. A chain bearing-plate 92 is arranged at the bottomof this pocket being" secured at intervals by the screws 92% It has agroove 93 along The chain carrier 94 is made up of the links 95 and 96.The links 96 have projections 99 which extend under plates 98 at the topof the guide plate 92', the plates '98 being secured by screws 97. Everyother link 96 is provided 'with a bunk 100, this bunk having a slant ortaper relatively to t-he'path of travel of the chain corresponding tothe'taper of the pail or tub.. The bunk is fixed in position on the link'by the pins 101 and secured in position by the screw. 102. The rear endof each bunk 'is-provided with a hook 103 which forms a1 driver for theblank carried by the bunk, one of these blanks as 'A being clearly shownin'Fig. 6. In order to assure the proper positioning of the blank on thebunk and against the hook or stop 103 yielding dogs 104 are providedeach side of the chain in the-path of the endso'fj the blank. These dogsare mounted arranged above the chain. 7 a rms 109 and; is secured to theframe by. means ofthe'posts 109 A. series of presser on pins 105 andhave the arms 106 to which thesprings 107-are attached. The blank cominginto contact with the dogs is forced back againstthe hook 103 and with afurther movement of the chain the dogs yield permitting the blank topass forward.

A frame formed of a pair .of bars 108 is feet 110, 1113 112 and 113are'moun'ted between the bars 108 by means of pins 114.

and consequentlygive to thestave exactly Each 'foot has a spring pm 115which is pivotally secured to the. foot and extends through a bar 116extending between the --framebars 108. Springs 117 are arranged betweenthe' presser feetand the. bars, 116

This has the the right increase in width or taper. v 'stave are made .ofsuch a size that when and tendto force the presser feet downwardly,Before the yielding dogs 104 are engaged by the blanks, the first foot110 has engaged the blank and holds it yieldingly on the bunk. As theblank is advanced the feet are brought into operation successively andare close enough together so that at least two of these are inengagement with the blank as the blank is advanced past the edge saws.

The chain is mounted on the sprocket wheels 118 and 119. The sprocketwheel 118 is carried by the shaft 120 and the sprocket Wheel 119 bytheshaft 121. The shaft 120 is mounted in bearings 122, in the frame(see Fig. 3). A beveled gear123 is fixed on the shaft 120 and meshes agear 124 fixed onthe shaft21. Thus the sprocket chain is driven from thesame shaft as the crank 80 which actuates the transfer lever 69.Consequently the movement of thetransfer lever is accurately timed withrelation to the chain and theblanks are movedonto the chain and underthe hook arms just be- .hind bunk so that as the chain advances theforward end of the succeeding bunk is carried under the blank, such acondition being shown by the blank A? in Fig. 4. The shaft. 121 isjournaled in bearings 125 carried by the frame (see Fig. 3). The frameto simplify the construction as clearly show-n in-Fig. 3. Y I

Thev edge saws 126 are carried bythe spindles 127 and the spindles 127by the bearings 128. The bearings 128 are mounted in the movable posts.129 and the posts 129 are mounted in the guides 130 011 the frame(see/Fig. '5) Projections131 extend downwardly from the post 129 throughthe frame and screws 132 extend through .these projections The screws132have the means of which the saws 126 maybe moved inwardly oroutwardly to adjust them to .is. separated on the'plane-of thesebearings various widths ofstaves. Drive pulleys 135 are mounted on thespindles 127 between the bearings 128 and belts 136 operate on thesepulleys to drive the saws. The saws are set at an angle so that theplanes of the saws intersect at what would be the center assembled they.will. exactly fill the circle for which theyare designed-1.. After {theThe staves have passed the edge saws they are carried by the chain tothe end of the machine where they are dropped, practically finished. I

Itis necessary, or at least very desirable for the saws to be in motiononly when feed ing of the blanks through the machine takes place. Wehave provideda .driving mechanism forthe various'saws WhlCll, requiresthat the saws be set-in operationbefore the feeding mechanism can beoperated and have I furtherprovided mechanism vthat will stop thefeeding mechanism upon the breaking of any belt driving the saws orcutters; The

driving scheme is shown in Fig.9. A drive of the :belt 187 in the usualmanner. A rock arm 144 engages a pin 144 on the shift rod 141. The rockarm 144 is mounted on a rock shaft 145 and this is carried by thehangers 145 A rock arm 146 is fixed on the zshaft 145 at the oppositeend from the rock arm 144 and a" link 147 connectslthe .rock arm 146'with the rock arm 148. The rock arm 148'is mounted 'on'la shaft 149. Theshaft 149 is carried in a bearing 150 extending from the frame. A handlever 151 is provided secured to the. lever 148 by means of which'thebelt'shiftermay be operated to throw the drivingmechanism into andout of action. A cone clutch 152 'is provided on the drive pulley 27(see Fig. 1). It is actuated by the usual levers 153 operating; on acone 154.

The cone has a collar or extension l55 witha pin 156 which engages forks157 of a lever "158. The lever 158 is mountedon a shaft 159'fand theshaft 159 is carried by the bear- -ings 160 '(see Fig, 9). A hand lever161 is secured to the shaft 159 bymeansof which the cone clutch may'be'thrown in orout so 7 as to start the feeding-mechanismof the machineor' throw it out. v I

In order to assure the starting of the saws before the feeding mechanismis thrown in,

we have provided the following'interlocking mechanism: An arm 162 ismounted on the shaft 149 in the path of an arm 163 mounted on the shaft159. .As shown-in-Fig; 1,-the parts'ar'e inposition for operation.Itwill be readily seenthat in order'to throwthe lever 151.and,consequently the arm 162 it will first be neces's'ary' to throw thearm 163 "forward jthusit is" necessary 'to move the forked end 156st) asto throw out the cone clutch prior to the stopping of; the saws by themovement of'the-lever1-51. In reversing this operationinstartingthemaehine, it is necessary to throw. the lever 151 and carrythe: arm 162 downwardly so thatthe arm163 may clear it before; it ispossible to'set the cone clutch.

It is desirable will automatically'stop the feeding mechanism when anysaw or cutter stops. Counto have mechanism that,

tershafts 164 and 165 are provided for drive I ing-the different parts.of the machine.

These are mounted in suitable hangers. ,A

' belt 166 drives the 'countershaft 164 and a .belt 167 the countershaft1.65,. These belts are driven from, the main drive shaft 138, pulleys168 beingprovided, on the shaft 138 for this purpose. The belts 136 aredrivenfrom pulleys 169 and 169" on the countershafts164 and 165respectively. belt17 2 is driven from a pulley17l on thecountershaft1-65 and operates the drive pulley 27.

Rider pulleys 17 3 are-provided for each of these rider pulleys arecarried by an arm 174pivotally mounted on a pin 175 with a the beltsdrivingasaw orcutter and each of;

suitable hanger. Each of theserider pulleys 3 are so weighted thatif abelt breaks they move under the influence of the .weight. Cables. 177move from the arms 174 over being guided by a hanger 17 9. The rod 178isconneetedwith a latch lever 180 (see Fig. I I

1) and this is carried by a pin 181. .The

latch lever has a hook 182: which engagesa' finger .183 on a weightedlever. 184.; The weighted'lever 184 is carried by a pin 185 suitablepulleys 176 to a rod 17 8, the rod on the frame an'dhasan6Xt6I1S1011'186 which I is" in the path of an arm 187 carriedby theshaft 159.

'When any belt driving asaw, therefore, breaks the rider pulley on thatbeltland its weighted arm are released and operating through itsconnecting cable operates the rod 7 178 releasing the weighted lever 184and this weighted lever moves thearm-187 thus swinging the shaft159andrthe-leve r 156 to release the cone clutch. In this waythexfeeding operation of the entire" machine is stopped immed'iately so:that no injury can result. 1 g v What is claimed as new tinuous motiona series of bunks on the cars 1161 having continuous motion and amovement past thesaws parallel tothe axis of the article to be formed,the. series'of bunks on'the carrier supporting the blank at anangle tothe axis of the article to be formed;
